1 IntroductionTo the owner or user : This service manual isintended to provide you, and the maintenance orservice technician, with the information needed toinstall, start up, clean, maintain and repair SCE275 is an ice machine that producescubed ice on a vertical freezing surface. The cubesfall into the ice storage bin where they break upinto individual SCE275 automatically maintains the level ofice by turning on when the ice level falls, andswitches off when the bin is unit is serviceable in place; the ice storage binand hood may be removed from the chassis toallow service access without removing the icemachine from its installed position.

6 Environmental LimitationsThe ice machine must be installed indoors in acontrolled Pressure20 PSI80 PSIV oltage (60 Hz) (50 Hz)207253 Operating the ice machine outside of the abovelimitations, or outdoors, is potentially damaging tothe machine, and it is misuse of the machine. Thismay void the Ice Systems are designed andmanufactured with the highest regard for safetyand performance. They meet or exceed thestandards of UL, NSF, and CULS cotsman assumes no liability or responsibility ofany kind for products manufactured by Scotsmanthat have been altered in any way, including theuse of any part and/or other components notspecifically approved by reserves the right to make designchanges and/or improvements at any and design are subject to changewithout on air cooled models is:Intake through the left front through the right front not install where this air flow is SCE275 has a removable cabinet.

7 Wheninstalled, the machine should have some extraclearance (18") on the left and right sides so that thecabinet may be easily removed when the machineis in 2003 Page 3 Air InAir OutInstallationWaterThe water supply for this ice machine has been incontact with many materials since it fell from thesky as rain. All rain is slightly acidic, and tends todissolve the materials it comes in contact water s journey to the ice machine, it hasflowed over and through the ground, been pickedup by a municipal or private pump, forced througha series of pipes of differing construction and mayhave been treated by the municipality providing means that there is no such thing as pure water.

8 All water contains some level of are two ways water carries the impurities:suspended and dissolved. Water filters can removethe suspended solids, but cannot remove thedissolved ice machines use more water than is madeinto ice, the excess amount is used to dilute theconcentration of minerals and rinse out the watersystem to keep the water scale from clogging upthe machine. That water rinse, combined withwater filters, prolongs the times between neededwater system water to the ice machine should be filters vary greatly in ability and one that filters out suspended solids to adimension of 5 microns or less. The finer the filterthe better, but finer filters may plug-up sooner thancourse ones.

9 It may be necessary to add a coursefilter ahead of the fine filter to prolong filter SCE275 is factory set for a water purge thatwill work in most water conditions. While theamount of purge is adjustable, only change it : Water use adjustments are customerconvenience adjustments; they are not factorydefects and are NOT covered by ice machine may be installed in the open orunder a counter. No clearance is required at thesides or top beyond what s needed to place thecabinet into position. Air cooled models blow air inand out through the grills at the front. Space isrequired for utility connections at the ice machine is not designed for outdooruse.

10 It must be installed indoors, in a controlledenvironment. The air and water temperaturesmust not exceed rated power is supplied through a cordconnected to the unit. All local codes must :1. Inspect the place where the ice machine is to beinstalled. Check for:space for the cabinet,water supply,drain availabilityand electrical power extension cords are allowed. The building draininlet must be lower than the drain outlet(s) at theback of the ice machine. The water supply musthave a hand shut off valve accessible when theunit is Determine the method of installation, is themachine to be installed under the counter? Is thedrain in the floor under the machine?
